Abstract

Cd1-хMnхTe(x=0.05) thin films have been obtained on mica substrates. The surface morphology of samples examined with scanning electron analytical microscope JEOL JSM 7600F and AFM. We obtained Cd1-xMnxTe (х=0.05) thin films of high perfection with smooth and glossy surface and having homogeneous composition of Cd, Te, Mn. The crystal structure of obtained samples was investigated by x-ray diffraction method. It has been found that the synthesized samples and films obtained on mica substrates have a polycrystalline structure and indicated on the base of cubic lattice. It has been studied the impact of γ-irradiation on structure of Cd1-хMnхTe (x=0.05) thin films. The samples were irradiated by γ-ray 3 times at T=300 K. After irradiation the intensity in X-ray diffraction patterns is changed. The x-ray patterns of non-irradiated samples showed all the characteristic scattering peaks. While, the x-ray patterns of irradiated sample appeared different. The irradiated samples showed less degree of crystallinity as evidenced by fewer peaks of lower intensity. We have investigated the influence of -radiation on electrophysical properties of Cd1-хMnхTе thin films at T=300 K. Samples were irradiated 3 times by γ-ray at Dϒ=1051krad doses. As a result the VAC has changed after irradiation in dependence of -irradiation dose. The resistance is changed too. After γ-irradiation till D=30krad doses the photosensitivity is increased but the further increasing of doses leads to disappearing of sensitivity.
